Title: Method for detecting defect
Inventor: KOBAYASHI KOTARO
IPC: G06T7/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To judge an actual shape of an opening part of a hole irrespective of an adhering foreign matter by projecting light on an object to be inspected which has a plurality of through holes, analyzing a gray image of the image and identifying the adhesion of the foreign matter from a density distribution or the like of the projected image. SOLUTION: A defect of a through hole of a shadow mask 2 or the like is detected, for example, by projecting a red transmission light and an incident ultraviolet light. A red light from a transmission light source 1 passes the shadow mask 2 and enters an image pickup element 7. A gray level of a picked image corresponds to a shape of the hole of the shadow mask 2. On the other hand, an ultraviolet light from an incident light source 3 is reflected by a dichroic mirror 5 which reflects, e.g. a light of a wavelength of approximately 400 nm or shorter, and is projected on the shadow mask 2. A fluorescence emitted from an adhering organic substance passes the dichroic mirror 5 and a filter 6 and enters the image pickup element 7. A wavelength of the fluorescence is mostly in a blue range.  Therefore, the shape of the hole can be detected from the image of the red light and, the presence/absence and a state of the adhering organic substance can be detected from the image of the blue light.

Abstract: PURPOSE:To simply attach a paper roll to a holder by constituting the holder core so that when a movable shaft is pushed in, its pushed-in state is maintained, and when it is pushed in again, the length projecting from a frame part is returned to the longest state. CONSTITUTION:In a state that a slide projection 29 of a turning shaft 19 is engaged into a groove 22 of an inner cylindrical body 15, the turning shaft 19 advances in the inner cylindrical body 15 by an energizing spring 20, therefore, a movable shaft 18 is pushed by the turning shaft 19 and advances until a projection 26 of the movable shaft 18 abuts on a terminal of the groove 22. In the holder core, the length projecting from a hole 16 of a frame part 14 becomes maximum. In such a state, when the movable shaft 18 is pushed in, the movable shaft 18 and the movable shaft 19 move backward, the turning shaft 19 turns by a prescribed angle, and the slide projection 29 is detached from the groove 22 of the inner cylindrical body 15 and becomes unadvanceable. The turning shaft 19 does not advance even by the energizing spring 20 and the movable shaft 18 holds its pushed-in state. In this case, when the movable shaft 18 is pushed in again, the turning shaft 19 turns by a prescribed angle, the slide projection 29 is engaged into the groove 22 of the inner cylindrical body 15 and becomes advanceable, and the movable shaft 18 also advances, therefore, it is returned to a state projected long from the hole 16 of the frame part 14.
